ROTARY ENGINE.

Application. filed October 18. 1924. Serial No. 744,374.

. This invention relates to rotary engines, and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a rotary engine of simple and durable form, and which may use an expanding gas, steam or air, as the motive Huid.

In the accompanying drawings:

Figure 1 is a transverse sectional view of the rotary engine.

Figure 2 is a sectional view thereof, cut on the line 2-2 of Figure 1.

Figure 3 is a sectional view thereof, cut on the line 3-3 of Figure 1.

Figure 4 is a fragmentary sectional view thereof, cut on the line 4-4 of Figure 1.

Figure 5 is a plan view of a ring used in the engine structure.

The engine structure comprises a casing 1, having a shaft 2 journaled thereinV and .passing transversely therethrough. A gear wheel 3 is located interiorly of the casing 1 and ixed to the same, and is concentrically mounted with relation to the shaft 2. Plates 4 and 5 are located interiorly of the casing 1, and are keyed or fixed upon the shaft 2. A crank shaft 6 is journaled in the plates 4 and 5, and is provided between the said lates with a crank 7. A gear wheel 8 is fixe to the vcrank shaft 6, and meshes with the teeth of the gear wheel 3. An oil tube 9 passes transversely through the side ofthe casing 1, and has its discharge end disposed above the gear wheels 8 and 3, andthe lubricant may be passed through the tube 9 for the purpose of lubricating the said gear wheels.

Jackets 10 are located between the plates 4 and 5, and curved cylinders'll are housed within the said jackets. Ports 12 are provided in the plate 5, and the said ports communicate at one end with the interiors of the cylinders 11. The plate 5 is plrovided with three sockets 13, with which t e ports 12 communicate. Rings 14 are ixed'to the side of the plate 5, but may move laterally with relation to the said late. The outer surface of each ring 14 ears against the inner surface of one of the side walls of the casing 1, `and the said ring is provided with bosses 15, which are received in the notch 13, and are provided with small compression rings. Springs 16 are interposed between the ring and the inner wall of the socket, and serve to hold the outer surface of the ring in close contact with the inner surface of the sidewall of the casing. The side wall of the casing is provided with threeopenings 17 and the openings through the bosses are adapted to register through the openings 17 as the ring is carried around with the plate 5, and during the operation of Vthe engine. The shaft. 2 is provided with ducts 18 and 19, which communicate with ducts 20 provided in the plate 5, with the spaces between the jackets 10 and the exterior surfaces of the cylinders 11. A cooling fluid, as for instance, water, may be drawn through the duct 18 and the duct 20, into the spaces and the cylinders, 'and the said fluid may be ejected through the duct 19 provided in the shaft 2. An arm 21 is pivoted at a point between its ends upon the shaft 2, and is located between the plates 4 and 5. The arm 21 is provided at one side with a lug 22, which is pivotally connected by means of a link 23, with the crank 7 hereinbefore described. Rods 24 are mounted at the ends of the arm 21 and carry pistons 25, which are slidably mounted in the cylinders 11. A spark plug 26 is mounted at the side of the casing 1, in one opening 17 and is adapted to register with the bosses 15, as the ring 14 turns with the plate 5. The other openings 17 function, one as an intake and the other as an exhaust.-

Therefore, it will be seen that as the plates 4 and 5 rotate with the shaft 2, the fuel is drawn in through the port 12 and enters the cylinders 11 successively. Each charge of fuel is carried around and is compressed by the swinging movement of the arm 21 and the movement of the piston 25 in the cylinder, and when the cylinders arrive successively at their respective compression points, the port 12 registers with the spark plug 26. Thus, the charge is exploded by the spark from the plug 26. At this point, the rpiston is held stationary by means o f the gears, and their connecting members or parts. Consequently, the cylinder is caused to move away from the piston, thus causing the movement of the shaft 2. The power is derived from the movement of the cylinder, which carries the plates 4 and 5, and which 'are attached rigidly to the shaft 2. The gear wheel 8 and the crank shaft 6 are turned by the movement of the plates 4 and 5.

between the jackets Havin thus described the invention, what each cylinder, an arm pivoted upon the is claime is: shaft and having rods connected with the A rotary engine comprisingta casing havpistons, said arm being provided with a lug', ing ports, ignition means in one of the ports, a link pivotally connected at one end with 6 a shaft journa-led in the casing, a gear Wheel the lug and pivotally connected at its other fixed to the casing and concentrically posiend With'the crank of the crank shaft, bosses tioned With relation to the shaft, a plate slidable in the ports of the plate, rings on mounted upon the shaft, a crank shaft Jourthe outer ends of the bosses, and springs asnaled in the plate, means oppositely connectsociated Wit-h. the bosses to hold the rings in 1G ing the gear Wheel with said crank shaft, engagement with the interior surface of the a pair of cylinders mounted on the plate, casing. said plate having ports leading to the cylin- In testimony Whereof I affix my signaders for admitting fuel to the cylinders from ture. the other of the first mentioned ports, a 15 pair of pistons, one slidably mounted in FRANK P.
